Let us consider Nature's remaining proposals to reclaim and reset the Biosphere and aerosol pollution. The authors challenged us to read their proposals and then discuss them. In the spirit of that challenge, I have let them do the talking (to be found in the quotes). But I do want to share a few final thoughts.
It's finally time to consider Safe and Just Earth System Boundaries proposals to reclaim and reset Earth Systems Boundaries. First up, the three most significant (at least in my view): climate, water, and nutrients. The authors of the paper in Nature challenged us to read their proposals and then discuss them. In the spirit of that challenge, I will let them do the talking.
In Part I, I presented a precis of the methodology the authors of Nature’s Earth System Boundaries had for the “… multiple levels of likelihoods to reflect underlying scientific uncertainties and variabilities.” As their findings “are meant as a transparent proposal for further debate” let’s now consider and debate the more contentious methodology underlying their proposed action – justice.
“Humans are taking colossal risks with the future of civilization and everything that lives on Earth.” So begins a report in Nature attempting to quantify Safe and Just Earth boundaries. The findings “are meant as a transparent proposal for further debate and refinement by scholars and wider society.” I took them at their word; let’s consider and then debate their proposals.
A study of chicken bones helps tell the story of our Anthropocene times, which is when Sapiens began making a significant impact on the planet. What lessons can we learn from how we have, so significantly, altered a bird to fit our needs?
